AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal

Wildlife Biology, EarlyView.
Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

Wildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...
